Well, I learned police in Britain probably stop people for random searches too often of something I didn't even know was illegal to carry there

. And getting life for being around the scene of the fight was kind of stupid...
But really, picking fights with people is obviously going to lead to an escalated fight of some kind, weapon or not. Would probably be better just to
make videos of people trying to talk things out or try to realize that physical fighting is pretty much meaningless and look at their situation from
different perspectives that don't incorporate oddly stabbing each other in the chest or legs.
And on the topic of weapon carrying of any sort, I don't see anything wrong with carrying a weapon if you're able to control yourself. I don't
advocate violence but somewhat limited self defense, hopefully not fatal, could be used for stopping a fight or attack of some kind.
